摘要:
In an air conditioning system comprising a heat source side machine for condensing a fluid which can change a phase between a liquid phase and a gas phase to a predetermined temperature and for supplying, and a plurality of user side machines more than half of which are disposed below said heat source side machine, in which piping is constructed in such a manner as to circulate the fluid supplied from said heat source side machine by using a difference in specific gravity between the liquid phase and the gas phase, between said heat source side machine and said user side machine and a cooling of said user side machine is performed by evaporating said fluid in said user side machine, the heat source side machine is provided with a control means for descending a set temperature of said fluid discharged from said heat source side machine after condensed by changing the operating capacity of said heat source side machine when a state that the temperature of said fluid returned back after evaporated in the user side machine at a time of a cooling is higher than a predetermined temperature continues for a predetermined time period. Accordingly, even when the cooling effect is insufficient due to the super-heated state of the fluid in the user side machine, the super-heated state of the fluid is resolved after the predetermined time has passed, thereby returning to the normal cooling

When one message data is transmitted dividedly at plural times to the same reception terminal, in the first transmission, a code specifying the terminal is transmitted, and then message data in a head portion of the message and a code indicating that succeeding data is present are transmitted, in the second transmission and thereafter, the code specifying the terminal is transmitted, and then data succeeding to the transmitted message data and a code indicating that the previously transmitted message data is continued from message data received at this time, and, unless the second transmission and thereafter is the last transmission, the message data having a code indicating that succeeding data is present are transmitted. The reception terminal receives transmitted data, and connects message data transmitted dividedly at plural times as one message data based on the code attached to the received message data.
摘要:
A vehicle monitoring system which may easily identify information transmitted from each of detecting devices without registration of identification information of the detecting devices and a transponder thereof are provided. A display is disposed in a distal end of the transponders all connected in series through a cable. Each of the detecting devices detects conditions in a predetermined portion of a vehicle and transmits vehicle information including measurement results, its own identification information and the number of transmissions. Each of the transponders determines whether the vehicle information transmitted from the detecting devices is received or not based on the identification information of the detecting devices registered in advance, and transmits the vehicle information to the transponder connected to the transmitting side or the display, when it determines that the vehicle information is to be received. Also, the each transponder receives the vehicle information transmitted from the transponder connected to the receiving side, updating the number of transmissions included in the vehicle information and transmits the vehicle information to the transponder connected to the transmitting side or the display.

An evaluation method for pneumatic tires and a system thereof, is provided, capable of appropriately evaluating an adverse effect, such as deterioration, of tire temperature by expressing severity of a temperature imposed on a member of tire made of rubber or the like in quantitative and convenient manners. Detection counts are calculated for each detected temperature according to a detection counts calculating unit 102 based on information of temperatures of pneumatic tires detected by a temperature sensor of a temperature detector 101. Temperature severity numbers of the pneumatic tires are calculated from a computing equation by a severity calculating unit 104 based on the detection counts and contribution coefficients of deterioration of tire rubber with temperatures stored in a contribution coefficient storage 103 as parameters. Using the calculated temperature severity number, a determination unit 105 determines thermal deterioration of the tire.

Provided is a thin film forming apparatus that can focus ion beams onto a target and reduce a manufacturing cost. In a thin film forming apparatus radiating an ion beam (17) from an ion source (22) toward a target (6) and forming a thin film on a surface of a substrate (5) with particles sputtered by the ion beam, the ion source (22) includes an electrode for extracting ions from plasma and accelerating the extracted ions. The electrode includes a plate-shaped accelerator electrode (26) in which a plurality of accelerator apertures are bored, and a plate-shaped decelerator electrode (27) in which a plurality of decelerator apertures are bored. The plurality of accelerator apertures and the plurality of decelerator apertures are aligned and offset to focus the ion beams (17).

A sensor system for a tire, which enables the installation condition of a sensor unit in a tire's air chamber to be know. A sensor system where a sensor unit is installed in a tire's air chamber has detecting means for detecting a relative change in the distance between the sensor unit and a position where the sensor unit is installed.
摘要:
In a pneumatic tire (20) on which a transponder (1) is mounted, a securing member (3) for securing the transponder (1) is fixed to an inner surface of the tire in an area (S) between a tire maximum-width position (A) and a bead toe (B). Thereby, a large centrifugal force and a large impact force do not act on the transponder (1) storing various pieces of information, and the transponder can be mounted quickly and securely. Also, the weight of the transponder is remarkably reduced, and thus uniformity of the tire (20) is enhanced. Additionally, dynamic balance correction is made easier. Even in a large tire, reduction in durability is minimized through suppressing heat generation and heat accumulation of the tire (20) due to the transponder (1) and the securing member (3).
摘要:
There is provided a vehicle abnormality detection method detecting an abnormal state in which a high temperature occurs due to maladjustment of a vehicle bearing mechanism section or vehicle brake mechanism section, and a device thereof and a sensor unit thereof. By use of the sensor unit 100 mounted in a rim 31, an air temperature within a tire 2 is sensed as a first temperature and a temperature (second temperature) of the rim 31 is sensed as a temperature related to at least one of a temperature of the vehicle bearing mechanism section and a temperature of the vehicle brake mechanism section 40. Then a temperature difference between the first and second temperatures is calculated and when the temperature difference is a predetermined value or more, it is determined that an abnormality has occurred in the vehicle bearing mechanism section or vehicle brake mechanism section 40. The abnormality is thus detected.
